Alcohol Effects The Endocrine System

Endocrine system controls the body's hormones and includes the pineal, pituitary, thyroid, and adrenal glands, and the ovaries or testes.

Alcohol sedates these glands, resulting in under-production of hormones; effects include increased susceptibility to allergies. Alcohol can effect sexual functioning in various ways. In low doses, it lowers inhibitions and may make a person feel sexier; but in higher doses, it can decrease sexual functioning: in men, by decreasing the frequency of erections, decreasing the maintenance of erections, decreasing penile size during erection, and increasing the amount of time between erections, in women by interfering with normal processes of sexual stimulation, and blocking orgasmic response.

With chronic and prolonged use of alcohol in men, there is a shrinkage of sex glands and an increase of the "female hormone" estrogen. This produces secondary sexual characteristics, such as enlarged breasts and a decrease in body hair. Prolonged use of alcohol can cause infertility in both men and women.
